Game 2, KW's Own Game Analysis, Attempting to Help GW Understand Control of the Center[June 3rd 2011]

8. Bd2
The correct way to break a pin is to move the Bishop to an intervening square, as here.

8. ... O-O
Knowing that he will exchange the Nc3 for his Bishop, Black takes the time to get his King away to safety before the attack.

9. Bd3
Trying to catch up on development on e4, and seeking to remove the pesky Bishop on f5.

9. ... Bxc3
When a piece is under attack, see if you can make a forcing move. The center will be closed, so Knights will be more influential than Bishops, until the endgame. White achieves the 2 Bishops, but Black has a lot of compensation. By Bxc3, Black further threatens Bxd2 with check, so White cannot take on f5, or he will be behind on the exchange after 10. Bxf5 Bxd2+ 11. Qxd2 exf5.
